McGrath - I can think of lots of differences between gay sex and smoking tobacco. Smokers treat the world as their ashtray - they throw butts where ever they want to. You can't say that about gays. And you don't have to walk through a cloud of gay sex to get into a building because all of the gays are gathered just outside the door because it's a "no-sex" building. Should I go on?

There is a big difference between public and private behavior. Anyone who wants to smoke behind closed doors where I don't have to breathe the poison is welcome to do so as far as I'm concerned. Doing it in public - no matter if it's gay sex or smoking - is a different thing altogether.
